A conductive film forming method is a method in which a conductive film is formed on a base material, and the method includes the steps of forming a film composed of copper particulates on a base material, subjecting the film to photo sintering, and applying plating to the photo-sintered film. Whereby, it is possible to form a conductive film on a base material by lowering irradiation energy of light in photo sintering even when the base material has low heat resistance. Since the conductive film includes a plated layer, electric resistance decreases.

The electroplating process of electroplating titanium alloy coating includes a direct current method and a pulse plating method. The direct current method characterized by lager sized grains and the pulse plating method characterized by smaller sized grains. The advantages of proposed electroplating processes are: a) low cost, b) very broad applications and c) relatively low number of the process steps. Unique combination of physical, mechanical and chemical properties makes the electroplating methods of titanium coating an attractive technology for medicine, biotechnology, sports, defense, aeronautic, and auto industries.

  • Publication number: 20120196032
    Abstract: A highly reliable electronic device that prevents entry of a plating solution via an external electrode and entry of moisture of external environment inside thereof, and generates no soldering defects or solder popping defects which are caused by precipitation of a glass component on a surface of the external electrode. The electrode structure of the electronic device is formed of Cu-baked electrode layers primarily composed of Cu, Cu plating layers formed on the Cu-baked electrode layers and which are processed by a recrystallization treatment, and upper-side plating layers formed on the Cu plating layers. After the Cu plating layers are formed, a heat treatment is performed at a temperature in the range of a temperature at which the Cu plating layers are recrystallized to a temperature at which glass contained in a conductive paste is not softened, so that the Cu plating layers are recrystallized.

    Abstract: A method for producing electrical components for electrical contacts, and such a component are provided. To achieve simpler production of a partial surface treatment, which likewise exhibits optimal current carrying capacity, with minimum material use of noble metals, the entirety of the components are provided with an electrically insulating passivation layer, and the passivation is then removed chemically or mechanically at the contact points of the components. The entire components are put into an electrolytic bath, and a noble metal is deposited only on the parts of the components from which the passivation layer has been removed.

  • Publication number: 20120164350
    Abstract: The invention relates to a process for the treatment of parts for creating a surface with areas with shiny and matte appearances, in which on the surface previously coated with a first layer of copper and a second layer of metal a selective etching of the second layer is performed, wherein the selective etching of the second layer is performed according to the area or areas to be glazed with respect to the rest of the part. The process allows a finish with areas of a different shine (from mirror shine to matte), the differences in thickness of which cannot be observed by the human eye without optical aids.

  • Publication number: 20120045691
    Abstract: Improved battery materials, and a process for producing such improved battery materials are disclosed. The materials and methods employ battery components based on porous lightweight non woven substrate materials that are coated with dispersions comprised of carbon nanotubes, conductive secondary particles (usually with an approximate diameter between about 0.5 nm to 100 microns), a binder and a solvent. The dispersions permeate the substrate's pores, and when cured, the carbon nanotubes form conductive bridges between the conductive secondary particles, and these in turn are held on the substrate by the binder. The net effect is to increase the battery's total active material and energy density. The permeated substrate may then be further treated to achieve the desired conductivity as needed. These materials and methods can produce improved lead acid and silver zinc batteries, as well as other types of batteries.
